SPECIFICATION To all whom it may concern;

Be it known that T, PETER F. GREENWOOD, a subject of the Queen of Great Britain and Ireland, and a resident of Oatasauqua, Lehigh county, Pennsylvania, have invented certain Improvements in Blanks for the Manufacture of Horseshocs,of which the followingisa specification.

The object of my invention is to so make a blank for horseshoes that it can be readily bent into proper form and subsequently finished by dieforging.

In the accompanying drawings, Figure 1 is a perspective view of a blank for a horseshoe made in accordance with my invention; Fig. 2, a transverse section of the same on theline 1 2, and Fig. 3 a transverse section on the line 3 4:.

in a separate application for a patent filed by me July 21, 1884, Serial No. 138,310,1l1ave described a process of making horseshoes by first rolling a'blank with the desired projections for the toe and heel calks and the indentations for the nail-head grooves,then bending this blank into horseshoeform, and finally finishing the same by a series of die-forging operations. It is preferable in the first instance to roll the blank in the manner shown in the accompanying drawings-that is to say, 0 with central projection, h, opposite end projections, z i, and intervening recessed or fiat portions, 0 6, these flat portions being greater in width than the projections h and i, as shown in Figs. 2 and 3 of the drawings. When the farming part of Letters Patent No. 320,350, dated June 16, 1885.

Application filed February 19, 1885.

(N0 model.)

blank is so made, it can be much more readily bent into horseshoe form than a blank of uniform width throughout, for in the latter case the blank has a tendency to bend at the points to w, leaving the central projection straight or nearly straight, owing to the greater bulk of metal at that point, whereas when the portions 6 e are wider than the projection h the latter bends readily in imparting the horseshoe form to the blank. Then the projections it and i, moreover, are narrower than the portions 6 of the blank, they are less likely to jam in the recesses of the dies than if the blank is of uniform width throughout, and this is an important feature, because in the event of the projections not reaching the bottoms of the recesses the work of the dies cannot be properly performed, and an imperfect shoe is the result.

I claim as my invention- The within-described blank for horseshoes, said blank consisting of central and end portions, it and i, with intermediate depressed portions, 6 e, wider than the said central and end portions, substantially as shown and de scribed.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

P. F. GREENVOOD.
